Abstract

L'invention porte sur un détecteur de position qui assure une linéarité des caractéristiques de sortie d'un angle de rotation et d'une tension de sortie de moyens d'actionnement. Une tête magnétique comporte une paire d'aimants (5) entre une paire de corps magnétiques (4) ayant des surfaces opposées, et un circuit magnétique fermé est formé par la paire de corps magnétiques (4) et la paire d'aimants (5). Un élément mobile (3) déplace la tête magnétique selon la quantité d'actionnement des moyens d'actionnement. Un détecteur magnétique (6) est disposé à l'intérieur du circuit magnétique fermé dans la tête magnétique pour détecter des changements du champ magnétique ayant fuit généré à l'intérieur du circuit magnétique fermé en raison du mouvement de l'élément mobile (3). Chaque corps magnétique (4) a une partie où la largeur varie progressivement.
